Acuity prototype intake

[Waitforit]

I'm interested to see how this intake performs with the intake on the passenger side. I always wondered why Honda put the cool side of the turbo on the passenger side as well.

Having the hot side of the turbo on the other side (American passenger side) would’ve made routing the dp and exhaust under the motor a pain in the ass maybe? I’m just guessing

I think this intake will probably provide the coldest temps possible (at the maf) however does that really matter? The intercooler should be able to scrub temp increases, even from an open element hot air intake.

if tracking. Sure. Stress the intercooler without adding an extra temp load from the intake. I guess. If on stock turbo, on a premium fuel ots tune but with an upgraded intercooler. Even if tracking, I can’t see the advantage tbh

pretty cool there’s another option tho

I’m not even gonna get into the weeds when it comes to the cats that foil wrap their intake piping. Cuz frankly that shit not only works but works very well.

not saying this intake is worthless. Just kinda niche. Good to have options tho. The child in me is pleased with the louder wooshy sounds

It's all about delta, though. 5F higher is 5F higher. An intercooler can only scrub so much, and a bigger intercooler than factory starts to have other tradeoffs (weight, lag, aero, radiator blocking).

I've seen huge iat reductions from the gold foil and wrapping the turbo and that's all due to keeping heat out of the intake tract when moving on track. Street use its even more noticeable because there are more chances for stagnant air flow.

I would imagine this intake would also help a ton. I'd still foil its runner and wrap the turbo, but I suspect it would be worth at least 5F on its own.

I still don't understand why Honda didn't just rotate the turbo from factory. It's just silly packaging as is.

It’s like that with the WRX fa20 top mounted intercooler but I’ve seen the 27won intake logs. Looked identical to the stock intake (maybe plus or minus 2 or 3f). Personally I wouldn’t even be worried

the turbo and how it’s placed. I’m sure there’s a reason for it. More than likely set that way for some kind of convenience?

I rather like this design and will probably swap my Infinity intake out for this. My Infinity butts up against the radiator fan motor end bell giving me little to no room for an upgraded radiator. The other thing I like about this intake is it opens up large area behind the radiator which should also help air flow. I think between it being a straight shot from the turbo and freeing up some under hood real estate it's a win win but guess we will see.

In fluid mechanics, a shorter and straighter flow would be less restrictive. So in theory, Acuity configuration would be better than others on market.

At higher rpm/speeds sure. The stock and after market intakes available aren’t designed poorly tho. The days of gaining 10whp from an intake are over. Oems got good at designing their intakes. Best we can hope for in modern times is cool wooshy sounds and like 2whp extra right before redline LOL

From a flow perspective and max power, yes.

The problem with factory design is not how it runs but where it runs, and most intakes don't solve the problem. Sitting idle is the most noticeable thing where you lose throttle response for a bit as you suck down warm air for a bit, but there's also the performance driving scenario where you sacrifice lag/time post brake zone, and especially on sweepers.

As to why the aftermarket is doing this...? Because oem did.

Why did the oem do it? I strongly suspect it's because of how the turbo housing sits coming off the engine and how they were trying to get the coolant lines and exhaust to run. They were limited to two positions for the turbo. The other direction would have worked, but the coolant lines would then have to run over the turbo and the exhaust would have to go further passenger side, which leads to some weight imbalance. They don't do this on the tc car... Because it doesn't need a functioning headlight.

I would argue they should have opened the option of a side mount position, but that's expensive from a block change perspective and would have increased cost a lot.

I would also assume the OEM configuration helps get everything up to temp fast, which is good for emissions and for people driving to the grocery store, etc.

My understanding is this is why they put the turbo in front to begin with.
